ABSTRACT:
There are provided an image display apparatus and method, which are capable of improving the operability of a white board function thereof, and allowing different devices to be operated on the same screen in a unified manner, and an information processing apparatus having the image display apparatus, and a storage medium storing a program for implementing the method. A control signal input device inputs a control signal. An operation signal output device outputs an operation signal to an external signal source. A memory section stores display screen information. A control signal switching section selectively switches use of the control signal from the control signal input device between a control signal for the display screen information stored in the memory device and the operation signal to be outputted from said operation signal output device.
